-14c1ams. (c1. 57-129) This invention relates 'toV an 'improved means for mounting' work* spindles vand particularly spindles of the type employed in'v textile machinery; V

A principal object of the invention isto provide a spindle mount which shall have 4the-properties both of resilience Yfor damping vibration and fof 'adjustability in a universal sense soas to permit ladjustment of the spindle in the frame or other supporting structure to a most favorable.opera tive position.

Another andbroader'object'of the invention is to provide a spindle mount of structural 'simplicity and high functional efciency.

"Still another object is to provide, in conjunction with a spindle mount of the aforesaid characteristics, a simple and readily operative gauge device whereby the spindle units of a textile spinning or like frame may be adjusted to correct settings with respect to the ring rails, regardless of variations in the spacing of the units in the frame, with each spindle located centrally of its associated ring in every position of rail travel.

The invention will be more readily understood by reference to the attached drawings, wherein:

Fig. 1 is a side elevational and partial sectional view illustrating aspindle havinga mount made in accordance with the invention;

Fig. 2 is an enlarged fragmentary sectional View illustrating the structural details of Athe mount;

Fig. 3 is a fragmentary sectional perspective view of an element of the mount structure;

Fig. v4 is a view in sectional perspective of, an element of the gauge device;

Fig. 5-is a view in perspective of another-element of the gauge device; l y e Fig. 6 is a fragmentary sectional view illustrating application of the device illustrated inFig. 4

the gauging operation; l

Fig. 7 is a fragmentary sectional View illustrating the manner in which the element illustrated in Fig. v5 is used in the gauging operation; Y

Fig. 8 is an enlarged fragmentary sectional view illustrating a detail of the gauging device,y and Fig. 9 is a fragmentary sectional view similar to Fig. 2- but illustrating a modification within the scope of the invention.

With reference to the drawings, the numeral I designates the spindle rail of a textile spinning or twister frame, and the numeral 2 the ring rail. Mounted in the rail I isa spindle, designated generally by the reference numeral y3, -andrcomprising in the present instance, a housing 41 and a blade 5 which may be journaled in the housing either flexibly, in accordance with the conventional practice, or rigidly. In accordance with the conventional practice the blade 5 is provided with a whorl 6. The housing 4 is provided externally withv threads 'I and a .nut 8 constitutingmeans for securing the spindlein the rraill, the `rail'be;

ing confined as hereinafter described between the inner or clamping face of the nut B and the confronting face of a shoulder Il at the upper end of the housing.

In accordance with the present invention an annular pad I2 of `resilient rubber or the like, preferably of 35 to 55 durorneter, finds4 a seat against the shoulder I I. In the present instance, an annular spacer element I3 is provided at the inner end of the bore of the pad, said spacer having a flange I4 confined between the pad andthe faceof the shoulder Il, and having an inner diameter corresponding to the external diameter of the portion I5 of the spindle housing 4 which immediately adjoins the shoulder I I. The spacer I3 thus functions to center the pad I2 accurately with respect to the axis of the spindle housing and makes it possible, by providing spacers of different thicknesses and internal diameters, to standardize the size of pad I2 independently of the diameter of the spindle housing. The spacers I3 may be in the form of turned metal or other rings, flanged as shown; but for economical adaptation to more than one size of spindle it is preferred to produce them from preformed flexible strip material of the desired cross sectional shape, said strip being cut into sections of appropriate lengths and the sections then being shaped to the required annular form. Such strip material may suitably be composed of rubber, plastic or the like.

As illustrated in Fig. 2 the lower face of the pad I2 is spherical in contour, and bonded to this face of the pad is a concave-convex facing plate I6, preferably of brass or brass-plated metal, conforming to the spherical contour of the face of the pad to which itis secured. The lower face of the plate I6 seats in the correspondingly contoured upper face of a cup Il, preferably also of metal, this cup element I'I having a lower flat face which seats against the upper surface of the rail I. vThe face plate I6 is adjustable in the spherical socket afforded by the cup I'I.

Below the ra'il I isa second resilient pad I8 similar in form to the pad I2 and having similar physical properties. The lower face of the pad I8 is of spherical contour and has bonded thereto a metal face plate I9 similar to the plate I6 described above. The spherical'lower face of the plate I9 seats in a spherical socket in the upper face of'a met-al cup member 2l, the lower face nds a bearing on theanut 8. The cup member 2I differs from the member Il, however, in that its inner peripheral edge ts neatly about the housing 4 so that the cup ZI is automatically centered with respect to the axis of the spindle. A suitable lock washer 9 is conned between the nut 8 and .cup member 2 I.

for forcibly urging said elements into clamping relation at opposite sides respectively of a support member, and two sets of elements interposed between the said clamping faces for connement under pressure between the respective clamping faces and the confronting faces of the opposite member, each of said sets comprising two elements having interseating convex and concave faces relatively adjustable on said seats so as to provide for angular adjustments of the spindle axis with respect to the support member, and one of the interseating elements of each set being composed of resilient material.

2. A spindle mount according to claim 1 wherein the resilient element is non-compressible and is free for distortion under the compressive force exerted by the clamping means.

3. A spindle mount according to claim 2 Wherein theresilient element is provided with a hard surface for seating engagement with the other element.

4. In a mount for work spindles, the combination with a housing comprising relatively adjustable clamping elements and adapted for installation in an aperture of a spindle supporting member with the said clamping elements at the opposite sides respectively of said member, said housing having clearance with the edges of said aperture, of means for relatively adjusting the said elements into clamping relation to the support member, and two sets of elements embracing the housing and interposed between the clamping elements for confinement under pressure between the respective elements and the confronting faces of the supporting member, each of said sets comprising two elements having interseating convex and concave faces relatively adjustable on said seats so as to provide for angular adjustments of the spindle axis with respect to the support member, and one of the said elements of each set closely embracing the housing so as to move with the housing when the latter is adjusted laterally in the said aperture, the other element of each set having clearance with the housing.

5. A spindle mount according to claim 4 wherein the element of each set which closely embraces the housing is the element of the set relatively remote from the said opposite sides of the support member.

6. A spindle mount according to claim 5 where-Y in one of the elements of each set is resilient.
